SIZE="2">2011 and 2013 Convertible Notes

In February 2006, we issued $2.5 billion principal amount of convertible notes due in 2011(the 2011 Convertible Notes) and $2.5 billion principal amount of convertible notes due in 2013 (the 2013 Convertible Notes) in a private placement. The 2011 Convertible Notes and the 2013 Convertible Notes were issued at parand pay interest at a rate of 0.125% and 0.375%, respectively. The 2011 Convertible Notes and the 2013 Convertible Notes may be convertible based on an initial conversion rate of 12.5247 shares and 12.5814 shares, respectively, per $1,000 principalamount of notes (which represents an initial conversion price of approximately $79.84 and $79.48 per share, respectively). These conversion rates will be adjusted if we make specified types of distributions or enter into certain other transactionsin respect to our common stock. The 2011 Convertible Notes and the 2013 Convertible Notes may only be converted: (i) during any calendar quarter if the closing price of our common stock exceeds 130% of the respective conversion price per shareduring a defined period at the end of the previous quarter, (ii) if we make specified distributions to holders of our common stock or specified corporate transactions occur or (iii) one month prior to the respective maturity date. Uponconversion, a holder would receive the conversion value equal to the conversion rate multiplied by the volume weighted average price of our common stock during a specified period following the conversion date. The conversion value will be paid in:(i) cash equal to the lesser of the principal amount of the note or the conversion value, as defined, and (ii) to the extent the conversion value exceeds the principal amount of the note, shares of our common stock, cash or a combinationof common stock and cash, at our option (the excess conversion value). In addition, upon a change in control, as defined, the holders may require us to purchase for cash all or a portion of their notes for 100% of the principal amount ofthe notes plus accrued and unpaid interest, if any. Debt issuance costs totaled approximately $89 million and are being amortized over the life of the notes using the effective interest method.

STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%">In connection with issuance of these convertible notes, a total of $3.0 billion of our common stock was repurchased under our stock repurchase program.Also concurrent with the issuance of the 2011 Convertible Notes and the 2013 Convertible Notes, we purchased convertible note hedges in private transactions. The convertible note hedges allow us to receive shares of our common stock and/or cash fromthe counterparties to the transactions equal to the amounts of common stock and/or cash related to the excess conversion value that we would issue and/or pay to the holders of the 2011 Convertible Notes and the 2013 Convertible Notes uponconversion. These transactions will terminate at the earlier of the maturity dates of the related notes or the first day none of the related notes remain outstanding due to conversion or otherwise. The cost of the convertible note hedges aggregatedapproximately $1.5 billion. The net proceeds received from the issuance of the 2011 and 2013 Convertible Notes, the repurchase of our common stock and the purchase of the convertible note hedges was $439 million.

STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%">Also concurrent with the issuance of the 2011 Convertible Notes and the 2013 Convertible Notes, we sold warrants to acquire shares of our common stock atan exercise price of $107.90 per share in a private placement. Pursuant to these transactions, warrants for approximately 31.3 million shares of our common stock may be settled in May 2011 and warrants for approximately 31.5 million sharesof our common stock may be settled in May 2013 (the settlement dates). If the average price of our common stock during a defined period ending on or about the respective settlement dates exceeds the exercise price of the warrants, thewarrants will be net settled, at our option, in cash or shares of our common stock. Proceeds received from the issuance of the warrants totaled approximately $774 million.

FACE="Times New Roman" SIZE="2">Because we have the choice of settling the convertible note hedges and warrants in cash or shares of our stock, and these contracts meet all of the applicable criteria for equity classification as outlined in EITF No.00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Companys

Own Stock, the cost of the convertible note hedges and net proceeds from the sale of the warrants are classified in stockholders equity inthe Consolidated Balance Sheets. In addition, because both of these contracts are classified in stockholders equity and are indexed to our own common stock, they are not accounted for as derivatives under SFAS No. 133, Accountingfor Derivative Instruments and Hedging Activities.
